OSSEC is a file integrity monitoring application that records changes to a server's file system to help detect and investigate an intrusion or change.
OSSEC is an open source tool that watches a server's file system. It documents changes to any file on the system and sends the change information to a remote OSSEC server. This change information provides extremely useful information when investigating security incidences.
Supported Operating Systems include:
- Mac OS X
- FreeBSD, OpenBSD, NetBSD
Units can sign up for the OSSEC service by submitting a HelpSU request.
